Abstract

The present invention is directed to a shaving system of the wet shave type comprising a blade member (one or more) and a structure which supports or holds the blade member and which has an external skin engaging portion in proximity to the blade member. The skin engaging portion includes an improved shaving aid composite which comprises a matrix of a water-insoluble polymer, an effective amount of a skin lubricating water-soluble polymer dispersed within the matrix, and a compatibilizer material that improves the compatibility of the water-soluble polymer with the water-insoluble polymer so as to reduce the domain size of the water-soluble polymer within the matrix. The improved shaving aid composite provides a greater and more sustained release of the water-soluble polymer during use while maintaining good mechanical integrity. The preferred shaving composite comprises about 15 to 40% polystyrene, about 40 to 80% polyethylene oxide, and about 0.5 to 15% compatibilizer material such as polyethylene oxide-polypropylene oxide copolymer.
